FRANK ARMSTRONG, OF BRIDGEPORT, CONNECTICUT.

BUCKLE.

SPECIFICATION forming part of Letters Patent No. 295,714, dated March 25, 1884.

Application filed August 18, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK ARMSTRONG, a

citizen of the United States, residing at Bridge-H port, Connecticut, have invented new and useful Improvements in Clamping Buckles, of which the following is a specification.

My invention relates to certain new and useful improvements in clampingbuckles, and

particularly to that class known as suspender? and belt buckles, and designedto adjust the length of the suspender over the shoul ders of the wearer. It has for its object to provide a buckle simple and effective in operation and economic of manufacture; and with these ends in view my invention consists of a buckle in which the clamping-jaws are provided with a slide adapted to cause the jaws to grip or release the web, accordingly as it is moved in one or the other direction, and also provided with a suitable guidebar for directing the movement of the web; and my invention further consists in specific details of construction hereinafter described and specifically claimed.

- In order that others skilled in the art to which my invention appertains may know how to make and use the same, I will proceed to describe its construction and operation, referring by letters to the accompanying drawings, in which- Figure 1 is a perspective view of one of my improved buckles, with the jaws open, ready to grasp the web,-shown in dotted lines. Fig. 2 is a similar view, with the jaws closed down upon and graspingthe web. Fig. 3 is a central section taken at the line at a: of Fig. 2; and Figs. 4 and 5 are perspective views, similar to Figs. 1 and 2, respectively, of a modified form of construction.

Similar letters denote like parts in the several figures.

A A.represent the jaws of the buckle, which are preferably made of a single piece, folded at B toform, with the sides, the frame of the buckle, and designed to stand slightly separated when in their normal condition, slightly open or separated, as shown at Figs. 1 and i. The j aw A is, by preference, extended slightly below the jaw A, and is grooved or fluted, as shown, to receive the end of jaw A, which is turned down slightly and serrated or roughened, as shown, to induce to a secure bite upon the web.

I C is a crossbar extending across theframe, to serve as a guide for the movement of the web, and D is a metallic slide, consisting of a strip having its ends bent so as to partially or shown, and serve to hold them in contact; or, in other words, the ends of the slideare so constructed and arranged that when the slide is moved away from the jaws A A, as shown at Figs. 1 and 4, the jaws A A are free to spring apart, and when moved toward the jaws, as shown at Figs. 2 and 5, the jaws A A will be forced toward each other and caused to grip the intervening web. At Figs. 1 and 2 I have shown the slide as arranged on the upper surface of the buckle over the web, while at Figs. 4 and 5 it is arranged underneath or behind the web. The effect, however, isthe samein both instances. I have also shown at Figs. 1 and 2 the jaw A extended into and forming a snap or other hook, E, to receive the connection of the button-loops of a Suspender, while at Figs. 4 and 5this hook is dispensed with, the purpose of these shown variations of construction being to indicate that the details may be considerably varied without departingfrom the spirit of my invention. It will be seen that the web may be passed over the portion B, under the bar C and slide D, and thence between the jaws A A, or reversed, or in any other desired way.

WVhen made in the form shown at Figs. 4 and 5, devoid of the snap-hook, the buckle may be advantageously used as an adjustable the garter-web to the cross-bar 0, drawing the other from the opposite direction through the bite of the jaws A A, and threading the excess of web between the bar C and back B in any desired manner.

It will be seen that the slide D, constructed and arranged as shown, not only serves as a means for operating thejaws A A, but also acts as a brace to strengthen the entire structure.

My improved clamp-buckle may be made by any approved process of working sheet metal, though I prefer to stamp it out of a single piece and then bend it at the point B. It may be made in two parts and joined in any suitable manner. It will also be observed that in making the buckle the blank is cut or punched out, so as to form a frame around a central opening,

wholly embrace the ends of the frame, as clearly belt, garter, or clasp by attaching one end of which permits the web to pass through the same in adjusting the buckle.

What I claim as new, and by Letters Patent, isl 1. A combined buckle frame and clamp consisting of the side and end bars, one or both of th latter having angular serrated flanges or projections to form clamping-jaws the whole formed of a single piece of sheet metal doubled upon itself and provided with a slide, substantially as set forth.

2. A combined buckle frame and clamp consisting of the side and end bars, one or both of the latter having angular serrated flanges to form clamping-jaws, the whole formed of a single piece of metal doubled upon itself and desire to secure provided with an operating-slide, D, in combination with the cross-bar G, substantially as and for the purpose set forth.

3. A combined buckle frame and clamp consisting of the side and end bars, one or both of the latter having angular serrated flanges or projections to form clamping-jaws, the whole formed of a single piece of metal doubled upon itself, in combination with the slide. D and a connecting-hook, E, substantially as and for the purpose set forth.

In testimony whereof Ihave hereunto set my hand in the presence of two subscribing Witnesses.

- FRANK ARMSTRONG.
